Coverage

Much better coverage than GSM

Our IoT network enables communication of small amounts of data over large distances. Compared to GSM (2G, 3G and 4G) NB-IoT provides 10x better coverage. There is also coverage in places that are difficult to reach, such as (in some cases even) underground. 

This good coverage is achieved by a high power density, because radio transmissions are concentrated in a narrow bandwidth of only 180 kHz. The Coverage Enhancement (CE) functionality also offers the possibility to repeat the transmission of a message if necessary. This is at the expense of a lower data rate and can have an effect on battery life. There are 3 different CE levels defined. CE level 0 is equal to the GSM coverage. CE level 1 is up to 10 dB higher gain and EC level 2 is up to 20 dB higher gain compared to GSM. 

Best network in the Netherlands

Our network is our right to exist. For years we have had the best tested 4G network in the Netherlands. We are also the first with a nationwide IoT network that uses NB-IoT. 

With more than 13,000 antennas, each of which can connect to more than 10,000 devices, we can offer you the best covering NB-IoT network in the Netherlands. In the past we only had 1800 MHz at our disposal, so for good coverage we had to install many more antennas than the operators, who also had 900 MHz at their disposal. Now we also have 900 MHz, which is also used by NB-IoT, and with the many extra antennas we have by far the highest coverage of all operators in The Netherlands. Of course, we are very proud of that. Because the coverage of NB-IoT is also many times better than GSM. NB-IoT even works in many places where your phone has no signal.

Each antenna can handle more than 10.000 connected devices. See the map to see the coverage and what the strength of the signal means for indoor, outdoor and in some cases even underground coverage.

Roaming

Deutsche Telekom has signed its first NarrowBand IoT (NB-IoT) roaming agreements with several European operator partners. The cooperation with Swisscom, Telia Company and Vodafone brings Mobile IoT roaming services to a further nine European countries. Deutsche Telekom currently offers NB-IoT roaming in nine of its own markets. The roaming agreements address customer demand for international coverage and service continuity for their fast-growing number of IoT devices. Only managed mobile services on licensed spectrum provide the network interoperability and secure IoT connections needed to meet future demand. Additional NB-IoT roaming agreements with further operator partners are expected in the coming months.

Seamless coverage is a key factor for companies looking to manufacture or deploy mobile IoT devices across multiple markets. Roaming is therefore important for many industries such as industrial asset tracking, where containers may need to be tracked across several international borders. Other examples come from the smart metering or waste management industries, where manufacturers usually produce smart meters or bin sensors in one country but require a single connectivity solution for these IoT devices to work in various markets.

“Our customers need a sustainable roaming environment for their Mobile IoT deployments to deliver a consistent service across international borders. This allows them to benefit from economies of scale as they continue to expand their business,” says Rami Avidan, responsible for IoT at Deutsche Telekom. “We are working hard to help accelerate the adoption of NB-IoT roaming in Europe and beyond. It is great to see the interoperability of our and our first partners’ networks now in place.”

Availability
NB-IoT roaming will shortly be available across 18 European countries. These include Deutsche Telekom’s networks in Germany, The Netherlands, Austria, Czech Republic, Slovakia, Hungary, Greece, Poland and Croatia; Swisscom’s network in Switzerland and Liechtenstein; Telia Company’s networks in Denmark, Finland, Norway and Sweden; as well as Vodafone’s networks in Spain, Italy, Germany, The Netherlands and the United Kingdom. Deutsche Telekom’s Connectivity Portfolio will be updated in the coming weeks to reflect the new roaming capabilities.
